Earlier this month, Adam Lamberttold news.com.au that there's a "sibling rivalry" vibe among the popular TV talent show's panel:

“It’s hard to explain. It’s almost like a sibling rivalry, healthy competition between all four of us. We tease each other so much backstage and it’s funny. We try to mess with each other in all ways. We make little digs on camera and backstage and I think we all get that this is a great, fun competition.”
